ATO Item RMA

Well I'm trying to figure out how to create a return and repair order for an ATO item (straight up ATO with a standard BOM not a CTO). If I use a line type that has a Scheduling Level of ""Inactive Demand with Reservations"" it barfs when I try to book the order. That Scheduling Level, when used with a non-ATO, item masks the line from being seen by MRP/ASCP which in a return and repair scenario is desired because you don't want the system to plan the work or material. Optimally I'd want that plus for the ATO line
